Here's my solution to the challenge. First, I use a scanner object. I wrap the scanner around System.in. In Java, that's an input string, and the scanner will now accept input from the command line. Next, I output a prompt. Notice I'm using print and not print line. And then I accept the input by calling the scanner object's next line method. I receive a string value, and then I use the double class's parse double method to parse that value. Now, I'm depending on the user typing a numeric value in, and if they get it wrong, it'll cause an exception and stop the program, but handling that sort of problem requires exception handling, which I'll talk about later in this series. Next, I do the same thing again. I accept another numeric value and save it as a double also, then I create a third double…
